Blyth played the flute, made musical instruments, and taught himself several European languages. He was particularly fond of the music of J.S. Bach. In 1924, he received a teaching certificate from London Day Training College. The same year, he married Annie Bercovitch, a university friend. Some accounts say they moved to India, where he taught for a while until he became unhappy with British colonial rule. Other scholars dismiss this episode, claiming it to have been invented by Blyth's mentor Suzuki Daisetsu. (Pinnington, 1997).

Korea (1925–1935)

In 1925, the Blyths moved to Korea (then under Japanese rule), where Blyth became Assistant Professor of English at Keijo University in Seoul. While in Korea, Blyth began to learn Japanese and Chinese, and studied Zen under the master Hanayama Taigi of Myōshin-ji Keijo Betsuin (Seoul). In 1933, he informally adopted a Korean student, paying for his studies in Korea and London. (Pinnington, 1997). His wife returned to England alone in 1934. He later followed her and they were divorced shortly thereafter, in 1935.

Japan (1936–1964)

Having returned to Seoul in 1936, Blyth remarried in 1937, to a Japanese woman named Kishima Tomiko (Pinnington, 1997), with whom he later had two daughters, Nana Blyth and Harumi Blyth. He moved to Kanazawa in Japan, and took a job as English teacher at the Fourth Higher School (later Kanazawa University).

When Britain declared war on Japan in December 1941, following the Japanese bombing of Pearl Harbor, bringing Japan into World War II, Blyth was interned as a British enemy alien. Although he expressed his sympathy for Japan and sought Japanese citizenship, this was denied. During his internment his extensive library was destroyed in an air raid.

Blyth and haiku

After early imagist interest in haiku the genre drew less attention in English, until after World War II, with the appearance of a number of influential volumes about Japanese haiku.

In 1949, with the publication in Japan of the first volume of Haiku, Blyth's four-volume work, haiku was introduced to the post-war Western world. Blyth produced a series of works on Zen, haiku, senryū, and on other forms of Japanese and Asian literature, the most significant being his Zen in English Literature and Oriental Classics (1942); his four-volume Haiku series (1949–52), dealing mostly with pre-modern haiku, though including Shiki; and his two-volume History of Haiku (1964). Today he is best known as a major interpreter of haiku to English speakers.

Present-day attitudes to Blyth's work vary: On the one hand, he is appreciated as a populariser of Japanese culture; on the other, his portrayals of haiku and Zen have sometimes been criticised as one-dimensional. Many contemporary Western writers of haiku were introduced to the genre through his works. These include the San Francisco and Beat Generation writers, such as Jack Kerouac, Gary Snyder, and Allen Ginsberg,[3] as well as J.D. Salinger. Many members of the international "haiku community" also got their first views of haiku from Blyth's books, including American author James W. Hackett (born 1929), Eric Amann, William J. Higginson, Anita Virgil, Jane Reichhold, and Lee Gurga. Some noted Blyth's distaste for haiku on more modern themes and his strong bias regarding a direct connection between haiku and Zen, a connection largely ignored by modern Japanese poets. (Bashō, in fact, felt that his devotion to haiku prevented him from realising enlightenment.[4] In addition, many classic Japanese haiku poets, including Chiyo-ni, Buson, and Issa were Pure Land rather than Zen Buddhists.) Blyth also did not view haiku by Japanese women favourably, downplaying their substantial contributions to the genre, especially during the Bashō era and the twentieth century. In just over 800 pages of text in his two volume History of Haiku, Blyth devotes a total of 16 pages to haiku by women, and even these pages are run through with negative comments about women as writers of haiku. "Women are said to be intuitive, and as they cannot think, we may hope this is so, but intuition, like patriotism, is not enough."[5] With respect to a verse ostensibly by Chi-yo he wrote, "Chiyo's authorship of this verse is doubtful, but so is whether women can write haiku." [6]

Although Blyth did not foresee the appearance of original haiku in languages other than Japanese when he began writing on the topic, and although he founded no school of verse, his works stimulated the writing of haiku in English. At the end of the second volume of his History of Haiku (1964), he remarked that "The latest development in the history of haiku is one which nobody foresaw...the writing of haiku outside Japan, not in the Japanese language." He followed that comment with a number of original verses in English by Hackett with whom Blyth corresponded.
